Re: SNR Drops - Errors Skyrocket! HELP!

The SNR dropped at 5:50PM last night (as shown in the graph posted above) and it started dropping at about 9:00AM today so I don't see any pattern at the moment. I'll keep monitoring to see if a pattern does emerge, however.

I have suspected the boiler, but after turning it off and turning it back on, it doesn't seem to have any effect. The router is next to a PC, but after turning it off, there is no change. Is there anything else you could suggest?

Re: SNR Drops - Errors Skyrocket! HELP!

Things like microwaves, anything powered by mains with one of those transformer blocks, anything electrical I'm afraid. As a quickish check you could operate every piece of electrical kit for a minute or so and see if anything triggered a drop. A boiler kicking in does seem a likely candidate, even though you seem to have ruled it out.
